Dragon Palace on the sea, under the Moon Pond.

A huge ring light illuminates the seabed dozens of meters deep as bright as day.

More than a dozen divers, operating various equipment, were constantly busy at one of the three sunken ships.

And beside them, there were even more men who were not wearing any protection or diving equipment, and only a pair of coarse shorts, swimming through the water like fish.

These people are all crew members from Zheng He's fleet.

Many of the crew members who arrived from the "backstage passage" of the Dragon Palace on the sea were once fishermen and pearl divers.

For them, even if this kind of system projection is not used, diving to a depth of tens of meters is as easy as eating a side dish. It just requires frequent ups and downs, which is more troublesome.

But now, they are essentially just projections. They don't have to breathe, don't have to worry about water pressure, and are almost invulnerable, making them very energetic underwater.

How deep can humans dive without wearing pressure-resistant suits?

It may be surprising to say it.

The method of diving without wearing a pressure-resistant suit or carrying scuba and other equipment is called free diving.

The current human free diving depth record is 214 meters.

Yes, humans can dive to more than 200 meters with their own bodies.

Free diving is the only way of diving that allows for rapid descent and rapid ascent without any restrictions, because if compressed air is inhaled under sea water, the strong air pressure can explode a person's lungs when floating up.

, makes people’s blood boil.

And all of this is due to human instinct.

When the part below the human nose and the upper part of the lips is immersed in water, human evolution, or a "legend" in the evolution of all mammals, is triggered - the "diving reflex."

The body automatically adjusts to a state suitable for underwater survival.

Blood begins to be rapidly supplied to the main parts of the human body, such as the brain, heart and other internal organs, while reducing the supply to the limbs.

Perhaps this is why washing your face with water can make you energetic, because your body thinks you are diving and supplies a large amount of blood and oxygen to your brain.

The ocean has always been dangerous to humans. Parents will also tell their children that water is dangerous and should not be approached easily.

But perhaps, humans are closer to the ocean than they think.

Moreover, humans can swim faster underwater than on the surface because there is no wave resistance.

If someone looked from above, they would see dozens of people at the scene, like mermaids, swimming around underwater at an astonishing speed.

Its free posture and swimming speed make other divers feel envious.

They themselves have to drag heavy ropes, wear bulky clothing and compressor pipes, and hang in the water.

Even so, they can't stay underwater for too long.

Human beings are able to stand at the top of the earth's ecology because human beings are a super-evolved terror machine, not because of the 0.5 goose combat effectiveness of modern otakus.

In many fields, human beings' own adjustment and control capabilities are actually far more reliable than various devices.

Thanks to the efforts of these dozens of people, a sunken ship that had been buried under the water and in the sand for more than two thousand years had been cleared of all attachments and sediments around it.

A sunken ship lies quietly in the water.

After 2,600 years, the structure of this sunken ship is still intact. Although the hull has been damaged, the structure of the entire ship has hardly been damaged.

There aren't even many signs of decay.

Messages came back one after another.

"The main structure is complete."

"The keel is not broken."

"The outer wall is damaged and the bottom is damaged."

"Foam materials are being used for partial repair and reinforcement..."

"The internal sediment siltation is serious, and the feasibility of floating the float is being evaluated."

"The internal sediment is too heavy and the floating of the pontoon may affect the hull. It is recommended to use foam materials to float."

In a room behind the Moon Pool in the Dragon Palace on the Sea, Pan Guoxiang watched those people working together in groups, as if they were on the shore, operating various modern instruments clumsily, and constantly evaluating them in his heart.

The most suitable place for the kind of foam material Gu Xiaobai invented before is underwater operations.

The material is ultra-light and has good strength. It can be used directly underwater and can protect the hull itself. It will not float up like many pontoons, which will damage the hull.

Operations under tens of meters of water are very concealed.

At this moment, everyone in the Sea Dragon Palace was attracted by Gu Xiaobai to the sea surface. No one noticed that some magical operations were taking place under the sea water.

Even if there was any noise under the water, it was directly covered up by the light, shadow and sound effects performed by the Dragon Palace on the Sea.

At this moment, Wang Guanshan issued a warning: "Report, Indonesian warship 357 is approaching!"

"Prevent them from approaching." Pan Guoxiang frowned deeply.

Gu Xiaobai needs to perform live, and the important task of directing the salvage falls on his shoulders.

Unfortunately, he is not an expert in deep-sea salvage. Although he is a little professional, he has been under great pressure in the past few months.

Fortunately, as a scientific researcher, the most powerful ability is not the amount of knowledge one has, but the ability to learn quickly and quickly change the knowledge system.

Within a few months, he read all the papers he could find related to deep-sea salvage, and finally became qualified for the salvage task.

However, if an Indonesian warship approaches at this time and discovers their secret...

Fortunately, after a few minutes, Wang Guanshan reported: "Ship 357 has left."

Before Pan Guoxiang could breathe a sigh of relief, he heard another heart-shrinking sound: "An Indonesian Navy helicopter is approaching..."

Did the Indonesian people discover something was wrong?

Or... the attack just now finally caused trouble?

For Pan Guoxiang, Gu Xiaobai was shot, and his first concern was Gu Xiaobai's safety.

But after that, what they were most worried about was how it might affect the salvage plan.

If the other side's military and police were stationed to investigate the matter, the impact on the salvage would be immeasurable.

With the military and police personnel from the other side stationed to investigate, how was the Sea Dragon Palace going to transport this sunken ship in such a swaggering manner!

Fortunately, after a while, Wang Guanshan said: "The other party has landed on the deck of the 357 frigate."

Pan Guoxiang breathed a sigh of relief again.

After going back and forth like this, Pan Guoxiang felt that he was about to develop kidney stones.

Time passed minute by minute, and finally, Pan Guoxiang received the most delightful feedback.

"You can float."

"Okay, everything is ready!"

Pan Guoxiang raised his head and looked at the other monitor in front of him.

Then he whispered: "Xiao Bai, you are ready and can come up at any time."

Then he paused again and said: "Xiao Bai, Ship 357 seems to be still monitoring us..."

At this moment, Gu Xiaobai is performing "Champion Overture" and "Expedition Song".

Hundreds of horses on horseback were dancing with swords, suddenly separated, suddenly gathered together, and suddenly rushed to kill each other, everyone watched intently.

It was as if he had been brought to the battlefield thousands of years ago.

I wish I could transform into a knight on horseback and gallop on the battlefield.

It wasn't until the "Expedition Song" was finished that Gu Xiaobai's voice came.
Chapter completed!
